Protect your app's sensitive content

Learn how to protect sensitive content in your Flutter app.

The SensitiveContent widget allows you to prevent screens that contain sensitive content (such as passwords) from being projected. To learn more, check out the following two-minute Widget of the Week video:

About the SensitiveContent widget

#

You can use the SensitiveContent widget in your app to set the content sensitivity of a child Widget to one of the following ContentSensitivity values: notSensitive, sensitive, or autoSensitive. Your chosen mode determines if the device screen should be obscured (blacked out) during media projection to protect sensitive data.

You can have as many SensitiveContent widgets in your app as you wish, but if any one of those widgets has a sensitive content value, then the entire screen is obscured during media projection. Thus, for most use cases, using multiple SensitiveContent widgets provides no advantage over having one SensitiveContent widget in your app’s widget tree.

This feature is available on Android API 35+ and has no effect on lower API versions or other platforms.

Using the SensitiveContent widget

#

Given some content that you want to protect from media screen share (for example, a MySensitiveContent() widget), you can wrap it with the SensitiveContent widget as shown in the following example:

dart
class MyWidget extends StatelessWidget {
  ...
  Widget build(BuildContext context) {
    return SensitiveContent(
      sensitivity: ContentSensitivity.sensitive,
      child: MySensitiveContent(),
    );
  }
}

When running on Android API 34 and below, the screen won't be obscured during media projection. The widget will exist in the tree but has no other effect, and you don't need to avoid usages of SensitiveContent on platforms that don't support this feature.
